The Difference a Day Makes

The final week of Meteorological Year 2018/19 had eight days in it. This year “Met Weeks” run from Sunday to Saturday – and Sunday is Temperature taking day. There is clearly an opportunity now to compare 2019/20 with last year, but I hope to present findings in a simpler, clearer fashion. I created some tables and graphs today that even I can’t understand.

Given that “climate emergency” is now mainstream, I’d like to keep a finger on the pulse, using data that are (I hope) trustworthy. (New Meteorological Year resolution – I’m going to try not to make any more silly calculation mistakes. I’ve found a few after posting, though they rarely exceed tenths of a degree and so have possibly gone unnoticed.)

One tidbit from today’s labours. Durham Tees, the “coldest” of the eleven stations last year, was the “warmest” in the first week of the new year. It returned a Mean temperature of 3.14°C above (my) Pre-Industrial baseline. Last year it averaged just 0.55 degrees above P-I, so in one week my “home patch” warmed at a rate 119 times higher than projected by the IPCC. Mumbai was second at 100 times warmer.

There is no need to panic. Six of the 10 Stations were cooler and cool enough to bring the IPCC “multiplier” down to x2 for “the Globe”. Phew!
